Hi guys

I have added a custom autocorrect to Word 2010, to convert the use of 99mTc to superscript the 99m part (apologies, but I can't seem to locate the superscript option in this message box and copying/pasting removed it anyway, but as shown in the line saying "symbolised by..." in this link http://en.wikipedia.org/wiki/Technetium-99m ).

This works to correct a variety of capitalisations, such as 99MTC, 99mTC and 99Mtc, even 99MtC, which is awesome.



However, it doesn't appear to work for 99mtc (the only combination I have tried that it hasn't worked), where no capitals are used at all. This is actually the one that would be most beneficial to use, as it requires less button pressing to make a letter capitalised.

I have tried adding this as an additional autocorrect, but it defaults to 99mTc in the autocorrect options in Options - Proofing.

Any ideas why this is the case, or how to fix it?

Thank you



Edit: More information

I've also just discovered a similar issue with 123I, where I have created an autocorrect to superscript the 123, which only works if I follow it with a capital I instead of a lowercase i. Obviously, with a single letter, there aren't many variations on this to test like the 99mTc example above. It appears though that word doesn't like autocorrect anything I add which is totally lowercase. Yet won't let me add a lower case example in Proofing is a example exists with a capital already.
